For the first time, the photoluminescence (PL) spectra of anodic porous alumina (P-Al) films impregnated with essentially non-fluorescent morin and morin–trypsin (Try) were investigated and compared with those of liquid solutions. It was found that their PL positions are similar to that of dye–Al3+ in ethanol solution, and the PL intensity of embedded dye–Try is much higher than that of embedded dye alone. We infer that the appearance of the PL band detected here is due to the formation of morin–Al complex in the holes of P-Al with the inner wall involved, and a likely luminescent mechanism is proposed to elucidate the PL enhancement phenomena due to the coexistence of morin and Try in the P-Al pores, which is confirmed by UV and FTIR measurements. Moreover, it is also found that the PL intensity increases with the pore size.

Co 100− x Sn x alloy nanowires were fabricated by electrodeposition of Co 2+ and Sn 2+ into anodic aluminum oxide (AAO) templates. X-ray diffraction results indicate that the crystal structures of the nanowires changed from polycrystal to amorphism, and then to polycrystal again with the increase of Sn content in the nanowires. Transmission electron microscopy result shows that the nanowires are about 50 nm in diameter and the aspect ratio is approximately 75. The magnetic response of the arrays was measured using vibrating sample magnetometry at room temperature. The results show that the coercivity and squareness with the magnetic field along the nanowire arrays decrease with the increase of the Sn content. Nanowires exhibit obviously uniaxial magnetic anisotropy, and the easy magnetizing axis is parallel to the nanowires owing to the large shape anisotropy.

Carbide of composition Gd2Fe17Cx compound with higher carbon concentration x = 2 was successfully prepared by the melt quenching. Fe-57 Mossbauer spectra of the carbides (x = 0, 1, 2) were measured at room temperature, the results show that the changing tendency of average hyperfine field and isomer shift is consistent with that of the carbides with x < 1.5. The effects of the interstitial carbon atoms in the Gd2Fe17 compound on the hyperfine parameters were discussed.
